METALLlC YARN AND TEXT SPECIFICATION forming part of Letters Patent No. 700,915, dated M. y 27, 1902.

Application filed April 9, 190] Serial No. 55,013. (N specimens.)

To all whont it may concern:

Be it known that I, LnoPoLD IIARMEL, a citizen of the Republic of France, residing in Boulzicourt, Ardennes, France, have invented certain new and useful Improvements in Metallic Yarns and Textile Fabrics, ofwhich the following is a specification.

My invention relates to fabrics adapted to produce in contact with the human body a voltaic action owing to the presence in the textile threads of metallic threads of different natures.

One method of carrying myinvention into practice consists in employing instead of copper and zinc threads textile threads of wool, cotton, silk, or the like twisted with line copper wires and with fine copper or other galvanized metal wires. For this purpose wires of soft galvanized steel are especially suitable. In order to obtain a greater degree of fineness, I may also employ a single thread only-that is to say, a fine galvanized copper wire from which the zinc is removed at intervals, so that alternate zinc and copper surfaces are obtained. The combination which I prefer consists in employing threads of copper and of aluminium or of partinium,

these latter being used instead of zinc or galvanized wires, partinium being more ductile and flexible than aluminium. In either case the metallic wires or threads are twisted with one, two, or more strands of wool or other textile material. The yarns thus prepared may be utilized for making fabrics, knitted goods, felts, or the like.

In the accompanying drawings, showing diagrammatically preferred arrangements of the various threads, Figure 1 shows the threads running transversely of the length of the fabric. Fig. 2 shows the threads running parallel with the length of the fabric.

In order to make these fabrics, I prefer to make, on the one hand, threads of a textile material put together and twisted with copper wires and, on the other hand, textile threads twisted and put together with aluminium wires, or galvanized metal wires, or zinc wires, and finallytextile threads without metal, the latter being designed to act as isolating-threads. These threads of pure textile material are arranged so as to separate the threads consisting of textile threads twisted or joined with copper wires from the textile threads twisted and joined with aluminium wires or zinc or galvanized metal wires, as shown in Figs. 1 and 2 of the drawings. 011 these figures the direction of the threads is different; but in both instances A means the aluminium, zinc, or other galvanized metal threads. 0 represents the copper Wires, and B represents the pure textile threads without metal, made of wool, cotton, silk, or the like.

Having now particularly described and ascertained the nature of my invention and in what manner the same is to be performed, I

declare that what I claim is 1. A fabric adapted to produce a voltaic action by contact with the human body, comprising threads made of textile material twisted with an electropositive metal, threads made of textile material twisted with an electronegative material, and pure textile threads isolating the electropositive material from the electronegative.

2. A fabric adapted to produce a voltaic action by contact with the human body, comprising threads made of textile material twisted with aluminium threads made of textile material twisted with copper, and pure textile threads isolating the electropositive material from the electronegative.

In witness whereof I have hereunto signed my name, this 25th day of March, 1901, in the presence of two subscyibing witnesses.

LEOPOLD HARMEL.
